Basically estimation and tracking is easy terminology by understanding definition of respective keywords. Additionally, in a viewpoint of each results, both may same exactly although have different meaning. There are two methods of tracking human pose, one is top-down, the other is bottom-up. In my comprehension estimation is usually used in an image and tracking is used in a video.
